# Cookie policy for QED42 ## Cookies, explained simply We're QED42 Engineering Pvt. Ltd. You can call us QED42 or QED if that's easier. This is where we explain what cookies are, which ones we use, why we use them, and how to tell us to stop. Last updated: 11 June 2026 Effective from: 11 June 2026 Applies to: [qed42.com](/) If you need to contact us about anything here, write to . ## What cookies are Cookies are small text files that a website places on your device. They help the site work, remember your choices, and show us how the site is being used. Some cookies are set by us. Others are set by trusted partners whose tools we use. That's the whole idea. Nothing more mysterious than that. ## How we ask you When you first visit qed42.com, you see a short banner. It lets you choose which cookies we may use. You can accept all, reject all non-essential cookies, or set your preferences by category. The accept and reject options sit side by side, with equal weight. We only place non-essential cookies after you say yes. Until then, they stay off. If you reject the non-essential ones, you can still use the site fully. Nothing here hides behind a cookie wall. Essential cookies keep the site secure and working, so they stay on. Everything else is your choice. ## Changing your mind You can change or withdraw your consent at any time. Use the cookie settings link in our footer to reopen your preferences. Withdrawing is as easy as agreeing. As soon as you update your settings, we stop the related data collection. ## The cookies we use **Cookie List** Cookies we set ourselves are first-party cookies.

Here are the main ones. We use Google Analytics 4 to see how you use the site so we can make it better. It measures things like how long you spend on a page and which pages you visit. We use Microsoft Clarity to understand usage patterns and see where people focus. We use HubSpot and LinkedIn for marketing analytics and audience insight. We use Cloudflare for security and performance. These partners help us measure the site and reach the right audiences. From time to time, we test new features and make small changes to how the site is delivered, and some cookies help keep your experience steady while we do. ### For users in India We operate from India, and we line our cookie practices up with the Digital Personal Data Protection Act, 2023 and its rules.

You can give, manage, and withdraw consent through the banner and the cookie settings link.

We ask for your consent before we place any non-essential cookie, and nothing non-essential loads until you choose. Your reject option carries the same weight as accept, and you can withdraw at any time. You can also ask to see, correct, or delete the personal data tied to these cookies, or object to how it is used. Write to . ### For users in the United Kingdom If you are in the UK, PECR and the UK GDPR apply, overseen by the Information Commissioner's Office. The approach is the same as for the EEA.

We ask before we set non-essential cookies, we tell you what each one does, and we let you change your mind. If your region gives you specific rights over this data, such as Brazil under the LGPD or Canada under PIPEDA, you can exercise them by writing to[ business@qed42.com](mailto:%20business@qed42.com). ### How to manage cookies You have two ways to stay in control.
